Hello all my name is Paul Miller, and I go by Lost. I am a welder and tattoo artist. I had been a 2 pack a day smoker for 13 years and just quit a little over two and a half months ago. So I started off vaping with an ego battery and top feed clearomizer. Needless to say while it did get me off the sick sticks I'd didn't last long. So I have been moving up little by little and made the jump to a true Haha mod DNA30 V3 with a Joytech Delta. Now is where the question comes in, I haven't had time to really search so if this is all ready out there just point me in that direction. But I'm moving into an RDA and while I know the basics of building coils. I have not found a 100% simple answer of what really changes the ohms in a coil. Is it the wire gauge or the number of coils. I'm looking to get a dual coil nemesis and I would like to run it at about .5 ohms which means I need two 1.0 ohm coils if I am understanding it all correctly. But what makes that 1 ohm coil? The wire gauge or number of coils.
